1、做成一个组件:
srccomponentssolution.vue
<template> <div class="solutions"> <div class="main_view"> <h1 class="title">{{title}}</h1> <div class="solutions_swiper"> <img src="../assets/imgs/direction.png" v-if="swiperIndex === 0" class="left" /> <img src="../assets/imgs/direction_active2.png" class="left" v-else @click.stop="changeIndex(‘left‘)" /> <img src="../assets/imgs/direction.png" v-if="swiperIndex === 2" class="right" /> <img src="../assets/imgs/direction_active2.png" class="right" v-else @click.stop="changeIndex(‘right‘)" /> <div class="swiper_all"> <div class="swiper_content"> <div class="swiper_container" id="swiper_container2"> <img v-for="item in all" :key="item" :src="item" /> </div> </div> </div> </div> </div> </div> </template> <script> export default { props: { all: "", title: "" }, data() { return { swiperIndex: 0, timer: ‘‘ }; }, methods: { changeIndex(direction) { //console.log(‘autoClick开始‘) //console.log(this.swiperIndex) var length = this.all.length; var swiper = document.getElementById("swiper_container2"); if (direction === "left") { if (this.swiperIndex > 0) { this.swiperIndex = this.swiperIndex - 1; } else if (this.swiperIndex==0) { direction ="right" } } else { if (this.swiperIndex < length - 1) { this.swiperIndex = this.swiperIndex + 1; } else if (this.swiperIndex>=length-1) { direction ="left"; this.swiperIndex=0; } } var sum = -(303 * this.swiperIndex); swiper.style.left = sum + "px"; } }, mounted() { this.timer = setInterval(this.changeIndex, 5000); }, beforeDestroy() { clearInterval(this.timer); }, }; </script> <style scoped> .swiper_all { background: url("../assets/imgs/cvs_phone.png") no-repeat center center; } </style>
2、其他vue文件中引用:
<template> <swiper title="特点" :all="all"></swiper> </template> <script> import swiper from "../components/solution"; export default { components: { swiper }, data() { return { swiperIndex: 0, all: [ require("../assets/imgs/sxbl01.png"), require("../assets/imgs/sxbl02.png"), require("../assets/imgs/sxbl03.png") ] }; }, created() { }, computed: {}, methods: {} }; </script>
